The Organizations’Psychological Environment Traits Modification When Adopting an Ethics and Compliance Program

Ethics and compliance programs have a direct linkage to key tenets of employee behaviors.The employee behaviors are building blocks of the organizations’psychological environment traits.They are characterized by role identity,self-awareness,motivation,and misconduct.It is crucial to unravel the diversity of the perspectives of the programs to design an appropriate framework of the relationship between ethics and compliance and organizational psychology.According to Weinstein(2019),“Compliance is a fundamental pillar of any corporate operation and culture,and it should be based upon the principles of transparency,impartiality,responsibility,integrity,professionalism and ethics”.While“Ethics goes beyond what the law requires.It involves doing the right thing and following both the spirit and not just the letter of the law”.The founding facets of effective ethics and compliance are culture,leaders,and risks management.Policies and procedures that integrate these factors reduce the risks of non-compliance.The organization psychological environment aligns with key characteristics of the workplace such as physical setting,culture,and job characteristics.Aspects such as noise,heat,and lighting measures may considerably impact concentration,thus affecting psychological well-being.According to Ruiz-Palomino,Martínez-Cañas,and Fontrodona(2013,p.173),ethical culture directly impacts an individual’s emotional and well-being,which characterizes organizational psychology.Culture and ethics influence perceived corporate support and social exchange,which trigger ethics and compliance.

Flexible Tropism of the Enterprises＇ Organization in Uncertain Competitive Environment

With the rapid development of the computer network, communication technology and the economic globalization, the competition environment faced by the enterprises has been more and more complicated. While the interactive competition becomes more and more fierce, it has been more and more difficult for enterprises to keep sustainable advantages in competition. In this paper the author mainly discusses the severe challenge of the new competition conditions to the traditional hierarchical structure and the reason why flexible organization will be the inevitable strategy selection of the enterprises.

Reconstructing Environmental Changes of a Coastal Lagoon with Coral Reefs in Southeastern Hainan Island

Coastal lagoons with small catchment basins are highly sensitive to natural processes and anthropogenic activities. To figure out the environmental changes of a coastal lagoon and its contribution to carbon burial, two sediment cores were collected in Xincun Lagoon, southeastern Hainan Island and (210) ~Pb activities, grain size parameters, total organic carbon(TOC), total nitrogen(TN), total inorganic carbon(TIC) and stable carbon isotopes(δ^(13)C) were measured. The results show that in 1770–1815, the decreasing water exchange capacity with outer open water, probably caused by the shifting and narrowing of the tidal inlet, not only diminished the currents and fined the sediments in the lagoon, but also reduced the organic matter of marine sources. From 1815 to 1950, the sedimentary environment of Xincun Lagoon was frequently influenced by storm events. These extreme events resulted in the high fluctuation of sediment grain size and sorting, as well as the great variation in contributions of terrestrial(higher plants, soils) and marine sources(phytoplankton, algae, seagrass). The extremely high content of TIC, compared to TOC before 1950 could be attributed to the large-scale coverage of coral reefs. However, with the boost of seawater aquaculture activities after 1970, the health growth of coral species was severely threatened, and corresponding production and inorganic carbon burial flux reduced. The apparent enhanced inorganic carbon burial rate after 1990 might result from the concomitant carbonate debris produced by seawater aquaculture. This result is important for local government long-term coastal management and environmental planning.

Ecology, Environment, Sustainability： The Development of the Environmental Movement in Israel

The article surveys the development of the environmental movement in Israel from the establishment of the state through the present day. Based on trends and transformations in the institutional planning system, it appears that activism by environmental movement organizations in Israel can be divided into three sub-periods： the establishment period, marked by the Sharon Plan, the founding of the Society for the Protection of Nature in Israel and MALRAZ--Council for the Prevention of Noise and Air Pollution in Israel, and the enactment of the Kanovitch Law and the National Parks and Nature Reserves Law （1963）. The next phase of institutionalization is characterized by the establishment of designated institutional bodies--the Nature Reserves Authority, the National Parks Authority and the Environmental Protection Service, and their integration into the national planning system. The institutionalization period concludes with the establishment of the Ministry of the Environment （1989） and the transition to the third period, sustainability. Prominent during this period is a trend toward multidimensional proactive environmental planning and policymaking, reaching across many areas and including extensive regulation As far as environmental organizations are concerned, these three periods comprised a framework of cultural action in which they developed, acted and shaped environmental discourse and practice in Israel. Based on other studies, the article offers a model that illustrates the development of the environmental movement while emphasizing the interaction between individual actors, local organizing and national organizations. Finally, some characteristics and insights regarding activism by environmental organizations in Israel are suggested.

Ozonation of o-phenylenediamine in the presence of hydrogen peroxide by high-gravity technology

The study herein investigated the effectiveness of simultaneous use of ozone and hydrogen peroxide(O_3/H_2O_2 process) to degrade o-phenylenediamine(o-PDA) in a simulated wastewater. A rotor–stator reactor(RSR) was employed to create a high-gravity environment in order to enhance ozone-liquid mass transfer rate and possibly improve the degradation rate of o-PDA. The degradation efficiency of o-PDA(η) as well as the overall gas-phase volumetric mass transfer coefficient(KGa) were determined under different operating conditions of H_2O_2 concentration, initial o-PDA concentration, temperature of reaction, initial p H and rotation speed of RSR in attempt to establish the optimal conditions. Chemical oxygen demand reduction rate(rCOD) of wastewater treated at a particular set of conditions was also analyzed. Additionally, the intermediate products of degradation were identified using a gas chromatography-mass spectrometer(GC/MS) to further evaluate the extent of o-PDA degradation as well as establish its possible degradation pathway. Results were validated by comparison with those of sole use of ozone(O_3 process), and it was noted that η, KGa and rCODachieved by O_3/H_2O_2 process was 24.4%,31.6% and 25.2% respectively higher than those of O_3 process, indicating that H_2O_2 can greatly enhance ozonation of o-PDA. This work further demonstrates that an RSR can significantly intensify ozone-liquid mass transfer rate and thus provides a feasible intensification means for the ozonation of o-PDA as well as other recalcitrant organics.

Identifying the influence of urbanization on soil organic matter content and p H from soil magnetic characteristics

Soil magnetic characteristics are correlated with soil p H and organic matter content. Analyzing soil magnetic characteristics, organic matter content and p H can indirectly evaluate soil pollution caused by human activities. This study analyzed the soil magnetic characteristics, organic matter content and p H in surface soil samples from different land use types in Shihezi city, a newly and rapidly developing oasis city in Xinjiang of China. The aims of this study were to explore the possible relationships among the soil magnetic parameters and thereby improve the understanding of influence of urbanization on soil properties. Eighty surface soil samples at the depth of 0–10 cm were collected from 29 July to 4 August 2013. The results showed that the magnetic minerals in surface soil were dominated by ferromagnetic minerals. Spatially, the magnetic susceptibility（χLF）, anhysteretic remanent magnetization susceptibility（χARM）, saturation isothermal remanent magnetization（SIRM） and ＂soft＂ isothermal remanent magnetization（SOFT） were found to be most dominant in the new northern urban area B（N-B）, followed by built-up areas（U）, suburban agricultural land（F）, and then the new northern urban area A（N-A）. The values of χLF, χARM, SIRM and SOFT were higher in the areas with high intensities of human activities and around the main roads. Meanwhile, the property ＂hard＂ isothermal remanent magnetization（HIRM） followed the order of U〉N-B〉F〉N-A. Built-up areas had an average p H value of 7.93, which was much higher than that in the new northern urban areas as well as in suburban agricultural land, due to the increased urban pollutant emissions. The average value of soil organic matter content in the whole study area was 34.69 g/kg, and the values in the new northern urban areas were much higher than those in the suburban agricultural land and built-up areas. For suburban agricultural land, soil organic matter content was significantly negatively correlated with χLF, and had no correlation with other magnetic parameters, since the soil was frequently ploughed. In the new northern urban areas（N-A and N-B）, there were significant positive correlations of soil organic matter contents with χARM, SIRM, SOFT and HIRM, because natural grasslands were not frequently turned over. For the built-up areas, soil organic matter contents were significantly positively correlated with χLF, χARM, SIRM and SOFT, but not significantly correlated with frequency-dependent susceptibility（χFD, expressed as a percentage） and HIRM, because the soil was not frequently turned over or influenced by human activities. The results showed that soil magnetic characteristics are related to the soil turnover time.

A Multi-Agent Expert System for Prevention of Child Abuse and Neglect

When a child abuse situation arises, the responsible agencies and entities in charge of response should be capable of providing a fast and personalized solution for the good of the child. This need leads the authors to consider the formation of dynamic virtual organizations tailored to each particular abuse case. In the authors＇ approach the partner selection of these collaborative networks is done through a software tool that combines two technologies from the field of artificial intelligence, specifically multi-agent systems and expert systems. In addition, these partners come from the breeding environment constituted by all the agencies or individuals, either in a region or locality, which have the potential of response.

Integrating Sustainable Development into Global Institutions:Reforming the United Nations

This article will briefly outline the origins,structure and functions of United Nations Environment Program and the Commission on Sustainable Development in the context of the goals of ecologically sustainable development(ESD).Economic development,social development and environmental protection form the three interconnected parts of ESD.The achievements of the key UN environmental institutions and programs in opening up the global system to civil society,the private sector and a diversity of actors and interests,promoting the role of poverty alleviation as part of ESD through the Millennium Development Goals,and facilitating important Multilateral Environmental Agreements should be recognized.However,with these notable exceptions,organizations such as United Nations Environment Program and the Commission on Sustainable Development have become weak in scientific and technical leadership,global policy,co-ordination(inside and outside the UN) and has few achievements in the international and national implementation of obligations and standards in Global Environmental Governance-including enforcement,compliance and effectiveness.This article will outline the key reasons for this inadequacy.Attention will also be focused on the way forward through of a new United Nations Environment Organization.This will require a clarification of purpose and function(within the UN system and as part of global governance structures) as well as consideration of whether it depends on system-wide UN reform.It is recommended that medium and long term strategies for reform are necessary.

Ecological and toxicological assessments of anthropogenic contaminants based on environmental metabolomics

There has long been a great concern with growing anthropogenic contaminants and their ecological and toxicological effects on living organisms and the surrounding environment for decades.Metabolomics,a functional readout of cellular activity,can capture organismal responses to various contaminant-related stressors,acquiring direct signatures to illustrate the environmental behaviours of anthropogenic contaminants better.This review entails the application of metabolomics to profile metabolic responses of environmental organisms,e.g.animals(rodents,fish,crustacean and earthworms)and microorganisms(bacteria,yeast and microalgae)to different anthropogenic contaminants,including heavy metals,nanomaterials,pesticides,pharmaceutical and personal products,persistent organic pollutants,and assesses their ecotoxicological impacts with regard to literature published in the recent five years.Contaminant-induced metabolism alteration and up/down-regulation of metabolic pathways are revealed in typical organisms.The obtained insights of variations in global metabolism provide a distinct understanding of how anthropogenic contaminants exert influences on specific metabolic pathways on living organisms.Thus with a novel ecotechnique of environmental metabolomics,risk assessments of anthropogenic contaminants are profoundly demonstrated.

Interactions between engineered nanoparticles and dissolved organic matter: A review on mechanisms and environmental effects

Dissolved organic matter（DOM） is ubiquitous in the environment and has high reactivity.Once engineered nanoparticles（ENPs） are released into natural systems, interactions of DOM with ENPs may significantly affect the fate and transport of ENPs, as well as the bioavailability and toxicity of ENPs to organisms. However, because of the complexity of DOM and the shortage of useful characterization methods, large knowledge gaps exist in our understanding of the interactions between DOM and ENPs. In this article, we systematically reviewed the interactions between DOM and ENPs, discussed the effects of DOM on the environmental behavior of ENPs, and described the changes in bioavailability and toxicity of ENPs caused by DOM. Critical evaluations of published references suggest further need for assessing and predicting the influences of DOM on the transport,transformation, bioavailability, and toxicity of ENPs in the environment.

Significance of adverse outcome pathways in biomarker-based environmental risk assessment in aquatic organisms

In environmental risk assessments（ERA）, biomarkers have been widely used as an early warning signal of environmental contamination. However, biomarker responses have limitation due to its low relevance to adverse outcomes（e.g., fluctuations in community structure, decreases in population size, and other similar ecobiologically relevant indicators of community structure and function）. To mitigate these limitations, the concept of adverse outcome pathways（AOPs） was developed. An AOP is an analytical, sequentially progressive pathway that links a molecular initiating event（MIE） to an adverse outcome. Recently, AOPs have been recognized as a potential informational tool by which the implications of molecular biomarkers in ERA can be better understood. To demonstrate the utility of AOPs in biomarker-based ERA, here we discuss a series of three different biological repercussions caused by exposure to benzo（a）pyrene（Ba P）, silver nanoparticles（Ag NPs）, and selenium（Se）. Using mainly aquatic invertebrates and selected vertebrates as model species, we focus on the development of the AOP concept. Aquatic organisms are suitable bioindicator species whose entire lifespans can be observed over a short period; moreover, these species can be studied on the molecular and population levels.Also, interspecific differences between aquatic organisms are important to consider in an AOP framework, since these differences are an integral part of the natural environment.The development of an environmental pollutant-mediated AOP may enable a better understanding of the effects of environmental pollutants in different scenarios in the diverse community of an ecosystem.

New insights into disruption of iron homeostasis by environmental pollutants

Among the numerous health conditions environmental pollutants can cause, chronic exposure to pollutants including persistent organic pollutants（POPs） and heavy metals has been shown to disturb a specific biological homeostatic process, the iron metabolism in human body. Disorders of iron metabolism are among the common diseases of humans and encompass a broad spectrum of diseases with different clinical manifestations, ranging from anemia to iron overload, and possibly to neurodegenerative diseases and cancer.Hepcidin–ferroportin（FPN） signaling is one of the key mechanisms responsible for iron supply, utilization, recycling, and storage, and recent studies demonstrated that exposure to environmental pollutants including POPs and heavy metals could lead to disruption of the hepcidin–FPN axis along with disordered systemic iron homeostasis and diseases. This article introduces and highlights the accompanying review article by Drs. Xu and Liu in this journal, which elaborates in detail the adverse effects of environmental pollutants on iron metabolism, and the mechanisms responsible for these toxicological outcomes. It also points out the knowledge gaps still existing in this subject matter. Research that will fill these gaps will improve our understanding of the issue and provide useful information to prevent or treat diseases induced by environmental pollutants.

Historical record of effects of human activities on absolute and relative concentrations of Polycyclic aromatic hydrocarbons(PAHs) in Lake Chao,China

Polycyclic aromatic hydrocarbons（PAHs）are attracting concern because of their potential toxicity,posing serious threats to health of humans and ecosystems（Kim et al.,2013;Zhao et al.,2016）.Generally,similar to other contaminants＇behaviors（Wu et al.,2001;Zhang et al.,2007,2008;Lu et al.,2009）,PAHs result from natural organic matter and activities of humans,the latter＇s contribution usually outweighing the inputs from other sources（Fernández et al.,2000;Srogi,2007）.

Integration of Chemical Methods and Biomarkers for Assessment of Chlorimuron-Ethyl Bioavailability in Soil

Bioavailability is a critical factor for assessing the environmental risk of organic pollutants in soil. In this study, extractions with 3 different solvents, including 2 aqueous solutions, calcium chloride(CaCl_2) and a phosphate buffer solution(PBS), and a mixture of aqueous solution and organic solvent, a PBS-methanol(8:2,volume/volume) mixture(PBS-M), were performed to assess the bioavailability of chlorimuron-ethyl in soil in comparison to a battery of toxicity tests in wheat seedlings. The results indicated that the peroxidase(POD) activity in wheat leaves after 7 d of exposure was one of the sensitive biomarkers of chlorimuron-ethyl in soil.The extractability of chlorimuron-ethyl by all the 3 solvents decreased with exposure time, and the rate of decrease of the PBS-M extraction between 1 and 7 d of exposure was substantially higher than those of the aqueous solution extractions. Chlorimuron-ethyl gradually changed from a water-soluble form into a soil organic matter(SOM)-bound form in the soil. The PBS extraction correlated best with the POD activity in the leaves after 7 d of exposure.
